The present invention relates to ironer rolls of the type used uponrotary ironers and especially to a novel padding for such rolls.

Among the objects of the present invention is to provide a novel paddingfor an ironing machine roll comprising a tubular section of resilientmaterial so formed as to give to the roll the desired compressibilityand flexibility.

A further object of the present invention is to provide a novel paddingfor ironing machine rolls of the type used on rotary ironers, thepadding being composed of a resilient material such as natural orcompounded synthetic rubber containing a multiplicity of substantiallycircular or tubular recesses on its inner or under surface opening intothe interior of the roll but giving a smooth uniform surface to theouter circumference or periphery.

The invention further comprehends a novel padding for an ironer rollcomposed of a resilient but substantially non-compressible material inwhich the inner surface is provided with a plurality of relativelyclosely spaced recesses extending outwardly therefrom to a point spacedfrom the outer circumference. These recesses are so disposed and of suchdimensions as to provide space for the resilient material to move intowhen the padding is under compression, but in nowise affect thesmoothness and uniform contour of the outer circumference.

Further objects are to provide a construction of maximum simplicity,efficiency, economy and ease of assembly and operation, and such furtherobjects, advantages and capabilities as will later more fully appear andare inherently possessed thereby.

The invention further resides in the construction, combination andarrangement of parts illustrated in the accompanying drawing, and whilethere is shown therein a preferred embodiment, it is to be understodthat the same is susceptible of modification and change, and comprehendsother details, arrangements of parts, features and constructions withoutdeparting from the spirit of the invention.

In the drawing:

Figure 1 is a perspective view of a rotary ironer of the type providedwith an ironer roll having mounted thereon the novel padding.

Figure 2 is a fragmentary enlarged view in perspective of the novelpadding.

Referring more particularly to-the embodiment selected to illustrate'the invention in the drawing, the novel invention is shown as appliedto an ironing machine I0 1 I 51 .9

. rotary type of ironer 2 in which the roll is adapted to be rotated andmoved into contact with an ironer shoe, roll or the like for the ironingoperation.

In order to properly perform the ironing operation, the roll is providedwith a novel padding 3 comprising a sleeve or tub r section adapted tobe slipped over the usual metal sleeve. forming the roll support. Thisnovel padding is formed or composed of a resilient material such asnatural or compounded synthetic rubber containing a multiplicity ofrelatively closely and substantially uniformly spaced circular ortubular recesses 4 on its inner circumference or periphery openinginwardly and extending outwardly but only partially through thethickness of the padding. As these recesses do not extend to the outercircumference or periphery of the padding, the exterior operatingsurface thereof is unaffected and presents a smooth, uniform surface tothe clothes to be ironed. This padding is then enclosed within the usualcover 5.

These circular or tubular recesses provide space forthe resilientmaterial to move into under compression during the ironing operation. Bythis construction, the resilient material of which the padding iscomposed and which is not compressible in the true sense of the wordwhen used in solid form, is given the desired flexibility andcompressibility to permit most effective ironing.

Having thus disclosed my invention, I claim: 1. In an ironing machineroll, a padding therefor consisting of a sleeveof resilient rubher andprovided with an imperforate outer surface and a plurality of uniformlyspaced tubular recesses opening into the interior of the roll andextending partially through the sleeve to allow for compressibility ofthe padding.

2. In an ironing machine roll, a padding therefor consisting of atubular section of resilient but normally non-compressible material, anda plurality of substantially tubular recesses uniformly spaced over theinner surface of the roll and extending outwardly to a point spaced fromthe outer circumference whereby the padding provides an imperforate andsmooth outer ironing surface.

3. In an ironing machine roll, a padding therefor consisting of a sleeveof resilient rubber provided with an outer smooth surface and circularrecesses uniformly spaced over the inner surface of the sleeve, saidrecesses opening inwardly and extending from the inner surface but partas employed on a way through the thickness of the material whereby "ti;pudding guides on lmperib'rate and REFERENCES CITED smoo ironing s ace.i
